dynamic dns (dyndns) update client that tries to be extensible, re-usable and efficient on network resources

Project description

Dyndnsc - dynamic dns update client

dyndnsc is both a script to be used directly as well as a re-usable and hopefully extensible python package for doing updates over http to dynamic dns services. This package currently focuses on supporting http based update protocols.


Basic example that should fit most peoples needs:

$ dyndnsc  --hostname --userid bob --password=fub4r

Are you using Miredo and want to assign a hostname dynamically to your ipv6 tunnel?

$ dyndnsc  --hostname --userid bob --method=teredo

Compatible protocols

Feel free to send pull requests to add more.

Compatible services

This list is incomplete, since there are for example a lot of dyndns2 compatible services out there, but we are not keeping a full list here. Also, due to current limitations in Dyndnsc (#4) it is not yet possible to use an arbitrary service with a compatible protocol (yet).


$ pip install dyndnsc

or, if you want to work using the source tarball:

$ python install


  • Python 2.6, 2.7, 3.2 or 3.3+


Documentation is available at


dyndnsc is currently still in alpha stage, which means that any interface can still change at any time. For this to change, it shall be sufficient to have documented use of this package which will necessitate stability (i.e. community process).
